PlE-ORUST-ROLMNG MACHBNE.

Application filed December 2 2,

simple, inexpensive, and improved mecha'n ism' for rolling plastic material, such as dough,

into thin and substantially circular layers, as

for a piecrust. We accomplishthis object by the device shown in the accompanying drawings, in which Figure 1 is an end elevation of a pie-machine; constructed accordi'ngto our invention. Fig. 2 is a front elevation of the same. Fig. 3 is a plan showing superimposed upon each other the successive outlines assumed by amass of material during its passage. through the device shown in Figs. 1 and 2.

In the construction shown in the drawings, a pair of horizontally-disposed cylindrical rollers 1 and 2 are journaled one above the other in the supporting-traine 3. pair of rollers 4 and 5 are mounted in-the 1' rame on parallel horizontal axes disposed at right angles to the axes of the rollers 1 and 2 and a considerable distance above saidrollers. "lhe rollers are all rigid on their shafts, and the rollers in each pair are geared together by the gears 6 and 7. The shaft 8 of the roller 2 and the shaft 9 of the roller 4 are journaled' in eccentric bearings 10 to permit the rollers to be adjusted relatively of each other. The shalt 1 1 of the rollcri is extended beyond the frame 3 at one end and carries a pulley 12, to which power is supplied by means of a belt. (Not shown in the drawings.) "The shaft 11 is geared to the shaft-13 of the roller 5 by means ofa pair of spiral gears 14. The gears 6 and 7 are formed with teeth of suitable shape to permit of the desired degree of adjustment between the re spective sets of rollers. Extending between the two sets of rollers is a suitably-inclined platform or chute 15, having its upper or guiding surlace so arranged that a nniss of dough alter passing the upper pair of rollers 4 and 5 will slide to a position of close proxiinity to the space between the lower pairol' rollers and with its elongated dimension pa 1'- Specification of Letters Patent.

allel with said ower rollers. The guidingsurface 15 is su tantially horizontal along the lower set of ,rbllers and extends into and along the trough of" said rollers, so that the material will be brought to rest in the proper position for being pushed sidewise between the lower rollers. Areceivingplatform 16 is arranged on the opposite side of the rollers 1 and 2 to receive the material after the same has passed said rollers.

The operation of the device shown is as follows: The space between the rollers 1' and 2 is first adjusted by means of the eccentric- I hearings to a width equal to the desired thickness of the pie-crust, while the rollers t and 5 are spaced considerably farther apart, the proper spacing being determined by experiment and depending somewhat upon the shape of the mass of material before delivcry to the upper rollers. When it is desired to form a pie-crust, a globular mass of dough, which in plan might be represented by the line 17 in Fig. 3, is droppedinto the space between the rollers 4 and 5. The rotation of draws the mass of dough through said'spaee and delivers it upon the guiding-surface 15. hasa somewhat elliptical outline, as shown The sheet of dough now at 18 in Fig. 3, the longest dimension emg transverse to the rollers 4 and 5. It then slides down the inclined guiding-surface to a position oppositdthe rolls 1 and 2, and a slightpush by the operator causes the sheet of dough to pass through the rolls 1 and 2 in the direction of its shortest diameter. The rolls 1 and 2 cause an elongationof the piece at right angles to that caused by the rolls 4 and 5, and the dough when delivered upon the latforin 16 is approximately the shape shown by the outline 19. The slabs of dough are then slid by the operator from the platform 16 upon pie-tins su ported by a suitable conveyer extending elow the roller 2, but not shown in the drawings. It will be seen that some of the construction shown may be altered'without departing from the spirit of our invention.

A device of vthe ing a frame; a pair of opposed rollers ourualed in said frame and geared to rotate in opposite directions and adapted to elongate class described, comprisgeared; and a stationary the said first a mass of plastic material passing between; a second pair of opposed rollers journaled at right angles to the first pair and similarly guidin surface in the frame, extending from the first pair of rollers into and along the trough of the second pair of rollers, for conveyin material from the first pair of rollers to the second, said. second pair of rollers being adapted to elongate the mass of material in a direction at an angle to the elongation effect-ed by the first pair, substantia ly as described.

A device of the class described, comprising a frame; a pair of opposed rollers journeled in said frame and geared to rotate in opposite directions and. adapted to elongate a mass of plastic material passing between; a second pair of opposed rollers journaled at right angles to the first pair, similarly geared, and located a considerable distance below pair of rollers; and an inclined stationary guiding-surface extending from thofirst pair of rollers into and along the trough of the second pair of rollers, for causing material, after passing between the first rollers, to slide to a position for delivery to the second rollers, to be elongated in a direction transverse to theelongation effected by the first rollers, substantially as described.
